Study of Adaptability on Silyl Terminated Polyether Based Non-Bleed Type Construction Sealants to Finishing Materials.

Abstract

It is known that pollution, cracks, sticky surface, bubbles and peeling of finishing materials may be occurred if a finishing material is painted on a construction sealant.It is also reported that using a non-bleed type sealant is effective to reduce risk of pollution of finishing material.This report is evaluation results of adaptability to finishing materials with a newly developed silyl terminated polyether based non-bleed type sealant.The evaluation on adhesion and pollution have been done with combinations of nine(9) sealants, six(6) finishing materials and w/wo barrier-primer.
